Key: DERBY-4646
URL: https://issues.apache.org/jira/browse/DERBY-4646
Project: Derby
Issue Type: Improvement
Components: Store
Affects Versions: 10.5.3.0, 10.5.2.0, 10.5.1.1, 10.4.2.0, 10.4.1.3,

Environment: Linux; Sun CVM phoneme_advanced_mr2
Reporter: Dag H. Wanvik
The small device platform we support based on CDC/Foundation 1.1 does not
support the NIO based method used by Derby to guarantee against dual boots of a
database by different VMs. It would be nice to have a way to guarantee against
this scenario.
Currently, one would have to use the property derby.database.forceDatabaseLock
with the ensuing hassle of cleaning away orphaned lock files.
The default behavior is "false", so then all Derby does if to print a warning
to derby.log and System.err.

Apparently this is not an issue on the Windows platform.
